XRD, TPR, XPS and BET methods are used to characterize the structure of catalysts and interaction between CuO/Cu and support. The results indicated that the Cu/Mn/Mg/K catalyst is much better than conventional Cu/Zn/Al catalyst in methanol decomposition, the supporters behave differently, and the catalyst supported on Al 2O 3 gives the best result.展开更多

文摘The activities of Cu/Mn/Mg/K catalyst with different supporter have been investigated in methanol decomposition reaction as function of copper support interaction, dispersion and valency structure of copper and pore structure of catalysts. XRD, TPR, XPS and BET methods are used to characterize the structure of catalysts and interaction between CuO/Cu and support. The results indicated that the Cu/Mn/Mg/K catalyst is much better than conventional Cu/Zn/Al catalyst in methanol decomposition, the supporters behave differently, and the catalyst supported on Al 2O 3 gives the best result.
